RILEY, OF FAYETTEVILLE, ARKANSAS DUST MOP CLEANING IVIACHINE Application filed February 27, 1931.

This invention relates to a machine designed for use in cleaning mops, brushes and similar devices used in dusting, brushing or mopping floors, walls and other building surfaces.

An important object of the invention is to provide a machine of this character having means for loosening the dust and dirt from the article being cleaned, novel means being provided for picking up the dust and dirt,

and carrying it to a place of deposit.

A still further object of the invention is to provide a machine wherein the dust and dirt will be confined to the interior of the machine, eliminating any possibility of the dust passing from the machine to become objectionable to the operator of the machine, or persons in the vicinity of the machine.

With the foregoing and other objects in 29 view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is an elevational view of a machine constructed in accordance with the invention, parts thereof being shown in cross section.

Figure 2 is a plan view of the machine.

Figure 3 is an enlarged sectional detail View illustrating the manner of securing the removable receiving pan to the dust bag.

Figure 4 is a fragmental elevational view of the connection between the bag and bottom.

Referring to the drawings in detail, the machine comprises a body portion indicated generally by the reference character 5, the body portion being hollow, providing a housing for the electric motor indicated by the reference character 7, and which is shown as mounted therein.

The reference character 8 designates a partition which is disposed within the upper end of the body portion 5, and spaced from the Serial No. 518,801.

upper end of the body portion, providing a fan housing at one end of the body portion 5.

Operating within the fan housing, is a suction fan 9 which is mounted on the shaft 10 of the motor. Communicating with the fan housing, is a discharge pipe'll that extends downwardly, where it is provided with laterally extended pins 12 that fit within the bayonet slots of the band 13 to which the bag 14 is connected, the pins and bayonet slots providing means for removably securing the bag in position on one end of the discharge pipe 11. The bag 14 is formed of cloth material'and has an open bottom that is normally closed by means of the receiver 15, which is formed ofpasteboard or paper material, so that it may be discarded when it becomes filled. with foreign matter.

This receiver is provided with a flange 15 at its upper end, which flange rests on the removable supporting ring 16, that carries the pins 16 which operate in bayonet slots formed in the ring member 17, that in turn is carried at the lower end of the bag 14. The ring 17 is clamped between the rin and g 7,

the latter ring being secured to the bracket 36, that is secured to one of the supporting legs 33. This ring 37 is also formed with a bayonet slot-at each side thereof to receive the pins 16.

The reference character 18 designates a container which is mounted on the body portion 5, the container providing a cleaning chamber for the mops or brushes being cleaned. The top of the cleaning chamber is open to permit the mops or brushes to be placed therein, while the bottom of the container is in communication with the fan housing to the end that foreign matter may be drawn from the cleaning chamber 18 by the action of the suction caused by the fan 9.

A screen indicated by the reference char acter 19 is positioned over the open bottom of the container 18 and acts to separate the larger particles of foreign matter in the passage of the dust and dirt laden air, from the container.

Extending laterally from the body portion 5, are arms 20 that have bearings 21 formed at their outer ends, in which bearings the vertical shaft 22 operates, the lower end of the shaft 22 being provided with a pulley 23, that receives motion from the motor shaft, through the belt 24: and small pulley 25, the latter pulley being mounted on the motor shaft.

As clearly shown by Figure 1 of the drawings, the upper end of the shaft 22 is provided with a beveled pinion 26 that meshes with the beveled pinion 27 mounted on the outer end of the shaft 28 which is mounted in suitable bearings formed in the, wall of the brush container 18. Associated with the shaft 28, is a shaft 29 that is disposed in parallel spaced relation with the shaft '28, the shaft 29 being also mounted in suitable bearings formed in the ends of the container 18.

Bristles 30 are mounted on the shafts 28 and 29, and provide brushes which operate in spaced relation with each other, to clean the mop or broom under operation. Mounted on the shaft 28, is a pinion 31 that meshes with the pinion 32, so that rotary movement of the shaft 28 is transmitted to the shaft 29, to rotate the brushes in opposite directions.

The machine is provided with supporting legs 83 in which the rollers 34 are mounted, so that the machine may be readily and easily moved from place to place.

The operation of the device is as follows:

The circuit to the electric. motor 7 is completed, causing the shaft of the motor to rotate rapidly. which in turn transmits movement to the brushes and suction fan 9. The brush or mop to be cleaned is now held in the container 18 and is moved vertieally'by the hand of the operator, with the result that the article being cleaned will be brushed by the rapidly rotating brushes. The dirt and dust will be dislodged from the article being cleaned, and the dirt and dust will be drawn through the fan housing, and through the discharge pipe 11, where it will be deposited in the bag 14, for removal when the bag becomes filled.

I claim:

A machine of the class described comprising a container having openings in the bottom thereof, a motor housing disposed directly under the container, a partition within'the motor housing and providing a fan compartment at one end of the motor housing and communicating with the container through the openings in the container, a fan operating in the fan compartment, arms extending laterally from the motor housing and arranged in vertical alignment, bearings at the ends of the arms, a vertical shaft mounted in the bearings, a pinion on one end of the shaft, a brush shaft having brushes thereon, mounted in the container and having a pinion mounted on one end thereof, said pinion meshing with the pinion mounted on one end of the vertical shaft to reas in own I have hereto affixed m si nature.
